摘要： The invention provides a method for producing an electrophotographic photosensitive member such that even if abnormal grown portions called spherical protrusions 203 exist on the surface of the photosensitive member, they do not appear on images, thus making it possible to considerably alleviate image defects. The method for producing the electrophotographic photosensitive member including layers each constituted by a non-single crystal material includes the steps of placing a substrate having a conductive surface in a film forming apparatus capable of being airtight-sealed under vacuum having evacuating means and raw material gas supplying means, and decomposing at least a raw material gas by a high frequency power to form a first layer constituted by at least a non-single crystal material on the substrate as a first step; exposing the substrate with the first layer formed thereon to a gas containing oxygen and water vapor as a second step; and decomposing at least a raw material gas by a high frequency power in the film forming apparatus to form on the first layer a second layer including an upper blocking layer constituted by a non-single crystal material as a third step.

摘要： As the surface layers of an electrophotographic photosensitive member, a first surface layer which satisfies a condition that a center line average surface roughness (Ra) ranges from 50 Å to 5000 Å and a second surface layer comprising a non-single-crystal carbon containing at least fluorine are laminated in this order. Thus, the generation of a defective image such as the dimness of an image or an image smearing can be suppressed under an environment of high temperature and high humidity without providing any heater even when an electrophotographic apparatus is repeatedly employed. Further, even when a toner of small particle size and excellent in its fixing characteristic is used, a cleaning characteristic can be improved and the fusion of the toner can be suppressed. Still further, even in an electrophotographic process with a frictional force raised for improving the cleaning characteristic, the cleaning characteristic can be improved and the fusion of the toner can be suppressed.
